Abstract It is crucial to make Complicated Information System (CIS) secure, interoperable, extensible and controllable. This paper presents a secure CIS architecture model to conduct the construction or reconstruction of CIS. It divides CIS into layers to reduce system complexity. Web service is adopted to fulfill interoperability and extensibility. It uses encryption support layer, security protection and reliability support layer to guarantee system security and stability. It uses system management layer to interact with other layers to make CIS administrable. A case study with performance statistic and network simulation show the model can satisfy the need of e-government without interfere with system performance. This model is apt to security-critical environment such as government, military and bank. Been properly simplified, it can be applied to relative simple information system too.
